The dorsal commences in front of the eye. The height of the body 

 is contained twice and three-fourths in the total length (without 

 caudal), the length of the head four times or four times and a half. 

 The greatest depth between the lateral line and the anal fin is less 

 than the length of the head. Scales minutely ciliated, those on the 

 head smaller than those on the body ; interorbital space flattish, scaly, 

 its width being equal to, or rather less than, the vertical diameter of 

 the orbit ; no spines or tubercles along the lateral line or the base of 

 the fins. Lateral line with a strong curve above the pectoral, the 

 depth of the curve being one-third of its width. Snout longer than 

 the orbit, the diameter of which is one-sixth or one-seventh of the 

 length of the head. Lower jaw prominent ; the length of the max- 

 illary is contained twice and a thii-d in the length of the head. Teeth 

 conical, pointed: upper jaw with eight strong ones on its anterior 

 half, and with a series of small ones on its posterior ; the lower with 

 seven or ten strong, widely-set teeth on each side. The lower eye

 a seiies of small smooth scales ; the distance between dorsal and 

 caudal is one-half of the depth of the free portion of the tail ; the 

 longest dorsal ra5\s are behind the middle of the fin, their length 

 being one-third or two-fifths of that of the head, and equal to that 

 of tlio pectoral. No spine before the anal. Uniform brown.
